Part 3 Weekly Inspections od
Safety Moment
• Situational Awareness
— Ability to observe, ID, process, and understand critical elements
within changing environments.
— This is a LEARNED BEHAVIOR.
— Requires a 360-degree mindset, constant evaluation of surroundings/activities
— Barriers include: false perceptions, being in a hurry, complacency, overload/fatigue,
fixation/preoccupation on distractions
• Tenets of Situational Awareness
— Know what's going on around you. Think about what might happen next.
— Have a plan of what you will do next. Know where you're going and have alternate routes and a plan
of action
— If something does not look right 4 DO SOMETHING ABOUT IT!
Safety
Task Hazard Assessments (THAs)
• Must complete THAs on
— Working around Heavy Equipment
— Working near water
— Vehicle Safety
— Unloading
— Working near Traffic (Construction Entrances)
• If circumstances change affecting THA, must update THA!
Safe Work Plan Requirements
• Safe Work Plan components
• Emergency Response — State Const. and CCS need
individual plans
Examp
Environmental Constraints/Commitments
• NCDOT has obtained a 404 for stream and wetland impacts
— During the construction of the project, no staging of equipment of
any kind is permitted in waters of the U.S. or protected riparian
buffers
— The Utility work does not cause any impacts (i.e., fill in waters)
• NCDOT has obtained a 401 certification to impact wetlands,
streams and Riparian Buffer Certification (Cape Fear)
— No erosion or sediment control devices in Zone 1, outside of the
approved project plans/impacts, anywhere on this project. Erosion
and sediment control devices shall be allowed in Zone 2 of the
buffers if Zone 1 is not compromised, and that discharge is released
as diffuse flow
— Utility work shall not cause impacts to waters or buffers, not already
permitted.
Environmental Constraints/Considerations Continued
• The Pigtoe Clam is an endangered species present in
Guilford county — avoid sediment releases as this could
impact this species
• Always inspect trees prior to removal for Bald Eagle nests or
Northern Long-eared Bats. If bird activity is noted, call Duke's
Migratory Bird Hotline at 1-800-573-3853
Goal — No Sediment Releases!
• Team Roles and Responsibilities
■ Duke/KCI Project Managers — Partner to ensure thorough and consistent communication
■ Duke Senior Technologist — "Boots on the ground" monitoring entire operation
■ Subcontractor - Must be aligned with goal of ZERO sediment releases
■ Duke SME — Regulatory communications and compliance "go -to"
■ AECOM Env Oversight— "Boots on the ground" monitoring Environmental performance
■ E&SC Inspector - Clear line of communication with the E&SC team
• Engineer of Record - Provide design modifications if installed BMPs fail to provide appropriate
protection
■ PNG Engineer of Record — Point of contact for gas operations
Don't be the weak link!

Sequencing for R-4707 Utility Relocation
• Confirm status/plan for stake out of ROW, PUE, DUE and jurisdictional areas prior to June 29.
• Delineate LOD and Install Construction Entrance and perimeter measures.
• Delineate and flag all ESAs with high visibility fencing or flagging and install excelsior wattles.
• Clear trees and shrubs within LOD — No grubbing. Spread mulch chips in 30 ft swath.
• Where easement is shared, construction of power lines shall take precedent over gas lines.
• Only trench area that can be installed and backfilled at end of day. Place excavated material on
high side of trench.
• Perimeter sediment control practices must be in place during all HDD operations — excavated
spoil must be stockpiled well away from ESA with perimeter protection and stabilized.
• NO land disturbance activities outside project limits.
Sequencing for R-4707 Utility Relocation continued
• If any disturbed areas occur where mulch does not restrain erosion, or wet/muddy conditions
cause soil disturbance, seed and stabilize according to required timeframes.
• Spoils from augering for proposed poles will be used for compaction back around the pole. Any
excess spoil will be recovered with industry standard lineman canvas bag for use at other poles.
• Contractor must maintain compliance with all plans and permits.
• Contractor shall be responsible for the control of sediment on -site. If existing E&SC measures
are insufficient, contractor must take steps necessary to keep sediment on -site (contact Duke
rep for approval).
• Perform E&SC inspections once every 7calendar days and within 24 hours of a 1 inch rain event.
Make necessary repairs to E&SC measures immediately per the plan.
• Inspections shall continue until permit is closed.
• After site is stabilized, remove temporary measures and provided permanent vegetation for all
disturbed areas.
• When project is complete, NCDEMLR must be notified to close out the E&SC plan. Once project
closed out, permittee must file electronic Notice of Termination (NOT).

Maintenance of E&SC Measures
• Make required repairs as needed immediately following
inspection. Give special attention to storm damage resulting
in end -runs and undermining.
• Replace materials that are damaged, decomposing, or are
otherwise ineffective.
• Remove accumulated sediment as needed. Do not allow for
sediment to accumulate higher than one-half of the height of
a barrier.
Erosion and Sediment Control Considerations
• Other subcontractors or third parties creating damage to
access routes (rutting), performing excavations or other land
disturbing operations within the approved plan's limits of
disturbance will return the ground surface to a well
compacted and graded surface suitable for positive drainage
and final stabilization/seeding.
Other Construction Site Pollutants
• Park all idle construction equipment
on secondary containment overnight
as illustrated in Figure
• All equipment secondary
containment should be located a
minimum of 125 feet from
environmentally sensitive areas
• Pumps and generators should be
placed on spill pads and located at
least 125 feet from streams
• Clean and remove equipment
pollutants immediately and
completely
• Store all oils, lubricants, fuels, or
other necessary chemicals in leak-
proof containers within secondary
containment at least 125 feet from
environmentally sensitive areas.
Other Construction Site Pollutants Continued
• Inspect construction vehicles, hauling trucks, service vehicles
and other motorized equipment for leakage daily prior to
operating onsite
• Look for pollutant spills or drips beneath equipment
throughout the project where vehicles track
• Report Oil spills > 25 gallons to the soil, any spill within 125 ft
of a water body, or ANY oil spilled to a water body causing a
sheen to 1-800-527-3853
Confirm this is proper protocol and that an Env Field Support does
not need to be called.
Be Storm Ready
• Leave all sites with land disturbing activities in a "storm ready
state."
• Properly secure all loose equipment. This should include light
plants, portable toilets, etc.
• Contractors should conduct extra inspections to ensure BMPs are
in place before they leave site for the day.
• Sites should be properly graded, and systems are stabilized and
can handle an influx of storm water.
• Site drainage features such as ditches, piping and silt fencing
have been maintained, cleaned and can handle an influx of water.
• Sediment containment basins have enough freeboard and can
handle heavy rains without overflowing.
Be Storm Ready Continued....
• Yard sump pumps are operating properly and can handle an influx of
storm water.
• Secondary containment features have been maintained and can handle
an influx of storm water.
• Once the rain passes, contractors or appropriate personnel shall inspect
and repair or manage erosion and sediment control measures as
necessary.
• Inspect sites with land -disturbing activities within 24-hours (if it is safe)
and document the inspection.
• If any sediment or other releases are identified, notify appropriate Duke
Energy personnel so such releases can be communicated to
appropriate environmental staff and regulatory agencies if appropriate.
Weekly Inspection Requirements
• What has to be inspected?
Visual monitoring of the following. -
Rain gauge maintained in good working order
• Ec Measures
• stormwater discharge outfalls (SDOs)
• Perimeter of site
• streams or wetlands onsite or offsite (where accessible)
• Ground stabilization measures
Once a week and after every rainfall event > 1.0 inch
